<P>PROBLEM TO BE SOLVED: To solve such a problem that conventional ferroelectricity has limited functions of a dielectric such as the occurrence of deterioration in electric signal storing characteristic and the performance of an electricity accumulating element because the conventional ferroelectricity originates from ion displacement. <P>SOLUTION: The function as the dielectric is developed by placing distribution of ions each having different valency in dipole arrangement to give the role of the positive charge to ions having larger valency compared to the average charge number in material and to give the role of the negative charge to ions having smaller valency compared to the average charge number in the material and arranging the ions in a position where the ion forms the dipole to form the dipole arrangement by the electron density. <P>COPYRIGHT: (C)2007,JPO&INPIT |
